Anti-interference, anti-vibration, anti-impact, high-strength and light-weight supporting structure suitable for urban railway vehicle transponder antenna

The invention provides an anti-interference, anti-vibration, anti-impact, high-strength and lightweight supporting structure suitable for a transponder antenna of an urban railway vehicle, which comprises an antenna bracket welding assembly and an antenna fixing plate which are connected with each other, the antenna bracket welding assembly is fixedly connected with a motor hanging seat of a framework cross beam, and the antenna fixing plate is fixedly connected with the transponder antenna. According to the invention, the defects that a transponder acquisition signal is easy to lose and a transponder antenna bracket cracks and even falls off to endanger driving safety due to large vibration of the end part of the framework can be effectively overcome. 本发明提供一种适用于城铁车辆应答器天线抗干扰抗振动冲击高强度轻量化支撑结构，包括：相连接的天线支架焊接组件和天线固定板，所述天线支架焊接组件与构架横梁的电机吊座固定连接，天线固定板与应答器天线固定连接。本发明可以有效解决应答器采集信号易缺失和构架端部振动大导致应答器天线支架出现裂纹甚至脱落危及行车安全的缺点。
